P015 Delays and drop-offs in the public sleep apnoea care pathway

Abstract Introduction Obstructive sleep apnoea (OSA) is a prevalent condition linked to cardiovascular and respiratory morbidity. Timely access to diagnosis and therapy remains a challenge. This audit evaluated the public referral pathway for suspected OSA in the Northern Adelaide Local Health Network (NALHN), focusing on delays, treatment uptake, and complications while awaiting care. Methods All OSA referrals to NALHN respiratory and sleep clinics from January–December 2023 were included. Patients were followed through triage, clinic review, sleep study, diagnosis, and PAP therapy initiation. Data were extracted from electronic records and clinic correspondence. Failed-to-attend cases were excluded. Percentages were calculated based on patients offered a clinic appointment at the time of the audit (Early 2024). Results Of 373 referrals, 86 (23%) had been offered a clinic appointment at the time of audit. Among them, 49% completed a sleep study, 47% received a diagnosis, and 36% commenced PAP therapy. The median referral-to-treatment time was 144 days (IQR 93–211). Government funding was approved in 71% of treated patients, with 77% reporting good adherence. Driving restrictions were documented in 18%. Multiple patients were admitted with respiratory issues while awaiting assessment or therapy. Conclusion Only one in four referrals progressed to clinic review within the audit period. Significant delays and hospitalizations occurred while patients waited for care, highlighting the need for improved resourcing and streamlined access to OSA services.
